Abstract

A compound actuator self-servo writes a hard disk. The compound actuator moves to track n+1. A first head on the compound actuator track follows on track n. The other heads servo write on track n+2. One of the other heads track follow on track n. The first head servo writes track n+2. The value of n is incremented by one, and the process repeats until the entire hard disk is servo written.
